They've died, they've killed and they've picked up lots of litter. Now we're three episodes into the new series, there are hints at where the Misfits' story is heading: a future where Simon's not such a geek, where Alisha doesn't heart Curtis, and where they've even got super-costumes.

The first series of Misfits seemed quite careful to keep the action contained. We occasionally got to see the five at home or out clubbing, but most of the stories saw the gang talking to each other (and killing the odd probation worker) in the community centre. This time, there have been a few more nods to the wider world – Simon's past in a mental health institute, Kelly's tattoo artist, Nathan's half-brother – but we're still pretty much covering similar ground, hanging out at the community centre. There's a contained scale to the action which is a real strength; you get that Breakfast Club feeling that they're stuck somewhere they don't really want to be, but they're making the most of it.

Which is not to suggest that Misfits is not ambitious - yesterday it was deservedly nominated for a South Bank Show award. Rewinding time pushed the storylines; time travel adds a whole extra layer of confusion and head-scratching fun. And Misfits certainly looks the part. It's one of the most stylish shows currently airing on British TV – even if you don't like the "tilt-shift" in-focus/out-of-focus way some of the scenes are shot (which I do), at least they're making an effort to make the series stand out.

The writing has also had some brilliant moments such as Nathan and Simon's "I just realised I haven't died this week", "It's only Thursday, there's still time"; and Nathan's line to his new-found younger brother: "We're a bit like the Mitchell brothers, only we're not bald, ugly and shit." Also memorable was Alisha's efforts to get her head round the time-travelling boyfriend issue: "How does this work? There's two of you?"

So where are things going now? Curtis's pilled-up flash-forward when he was tripping in the club was a great way to drop some hints about where the rest of the series is going: the gang in capes, everyone hanging up and Curtis getting physical with someone who isn't Alisha. Thanks to the revelation last week that Superhoodie is in fact "Future Simon", we've also learned that the world is going to find out about the "Asbo Five" courtesy of Alisha, who watched some clips of her future self being interviewed on TV about her powers ("Do we become famous? It's got to be better than picking up litter …"). So not only can Simon turn invisible, jump off buildings, chuck paper planes with uncanny accuracy and time-travel – he's also worked out a way to bring his future laptop back with him. Handy.

But why is he back? Has he come to save Alisha because something has happened to her in his version of the future? As he puts it: "There are things that need to happen at certain times. I'm here to make sure they do." But what things? And how can he change them? Your theories below, please.

Your thoughts would also be appreciated on the timeline of the second series. Everything has taken place within a few weeks – does this help you accept the shifts in the relationships last week? It did seem a bit quick for Alisha to fall for Future Simon – but then again, she hasn't been going out with Curtis for that long; and it looks like he's just as intrigued by Nikki, the woman he sees himself with on the rooftop.

And there's also a question over the Superhoodie/Future Simon revelation: was it too close to the Future Hiro storyline in Heroes for you? Perhaps one of the downsides of focusing on such a small cast is that it's difficult to introduce new characters with any real impact unless they're already connected to the existing cast – a variant on the Darth Vader "I am your father" situation; a whole universe, and everyone's related.
